17 Claim.

This invention relates to a data reproducing machine and more particularly to a machine capable of reproducing coded data representations from one type of data carrying medium to another and diflerent type of data carrying medium. 3

The data carrying mediums may be of the types or forms suitably adapted for the automatic control of well-known types of machines,

such as statical machines. typewriting machines,

or the like. For example, in mechanized accounting system, employing various types of known statistical machines, record cards, having data representations disposed thereon, are used for controlling the operations of the machines used in such systems; when utilizing the wellknown Hollerith type of statistical card, the data representations usually are in the forms of perforations, which are formed at diiierent columnar index point positions. The codes employed may be of diflerent types, such as the combinational perforation code system, or singleperforation code system.

It has been suggested to employ diii'erent types of control records other than the perforated record cards, for controlling the machines referred to, for example, one type suggested, being a record medium having a layer of light sensitive emulsion disposed thereon which, when exposed to suitable recording mechanisms, and properly conditioned, is adapted to bear the data representations in the form of imperi'orate control spots disposed in various code positions thereon. These control spots, or index points, may then serve as light modifying or modulating areas for controlling the statistical or other operations of the machines.

It hasbeen found that. when it is desired to employ such machines controlled by diiierent types of control records, provision must be made, whereby the data representations carried by one type of records can be reproduced and formed on the other type of records. or vice versa. To simplify the description of the present invention, theillustration and disclosure thereof, will be limited to suitable mechanism which may be conditioned, whereby the data representations, in

anism, which elements can be conditioned so that the data representations on the record cards are sensed and reproduced as control spots on the photographic control records, or, so that the data representations in the form of control spots on the photographic control records are sensed and reproduced as suitable index points on the record cards, and for illustrative purposes shown as perforations disposed in diiferential index point positions on the record cards.

Another object of the present invention is the provision of common control driving means and circuits, which are called into action irrespective of the conditioning of the machine, whereby the data is sensed on the individual record cards 'and reproduced on the light sensitive record medium, or if the data is sensed on the light sensitive medium, reproduced on the individual record cards.

Another object oi the present invention resides in the provision of electrical sensing means and electromagnetically controlled perforating means for the record card, and sensing means comprising light rays and light responsive means, and photographically recording means for the film record, and means to convert the electrical values into light values, or vice versa.

Another object resides in the provision of manually positionable means for storing data which may be recorded on the mediums at the same time, and in addition to, the data sensed and reproduced.

Other objects of the invention will be pointed out in the following description and claims and illustrated in the accompanying drawings, which disclose, by way of example, the principle of the invention and the best mode, which has been contemplated, of applying that principle.

General description Briefly and broadly, the instant application discloses, by way of illustration,'record card sensing and recording means, photographic film sensing and recording means, and associated control elements, all of which when'suitably conditioned render the device effective, (1 for sensing the data representations, in the form of.

perforations on the record card, and thereafter controlling the film recording means, at differthe-record cards in the form of diflerentially displaced perforations or the like.

Manually settable devices are also provided, which have positionable elements to represent any desired data, and are effective to control I the selected record medium recording. means to effect recording of the data, upon the selected record medium, corresponding to the data set up in the said devices, in addition to the recording of the data corresponding to thepdata sensed on the related control record medium.

Referring nowtoFig. l, the data reproducing mechanism, or device, is shown to comprise a record card magazine, or supply hopper M, from which the cards are fed singly by the card feeding means, comprising. inpart, the card picker 41 and 43 and actuating arm 68 therefonto the feed rollers 33 to 33, past the card sensing station including the brushes H3, to-the card drum I20, feed rollers I22 and I23, and card stacking magazine or hopper N. Interpose'd between feed rollers 33, 3| and 32, 33 is shown one suitable type of card recording means, for example, the

punch plungers 33 and control magnets 33 there for.

The photographic film I30 is fed, by means of the driving sprockets 2I3, from a supply reel 20! pasta suitable sensing and recording station, comprising the individual light sources I13, asso- "ciated light conducting quartz rods I11 and I82,

' tocells and suitable lightresponsive'means, such as pho- I33; to a suitably disposed take-upreel 2M. 1

Suitable control and conditioning means are provided so that the control units referred to can be conditioned whereby the cards are fed,

singly, from the supply magazine to the card sensing station. At the said card sensing station,- the perforations on the record cards are sensed, at'diflerential times, for controlling the energization of the corresponding individual light sources, at the said differential times, for efiecting the recording of'the control spots on thephotographic film. The mentioned control units can alsobe conditioned so that thecontrol, spots onthe photographic film are sensed, at differential times for controlling the operation of the associated photocells, which photocells, in turn, are

effective to control the card perforating control magnets, thereby electing perforation of the record cards in accordance with the data sensed.

By referring to Figs 7 and 8, facsimiles of portions of the perforated record cards and recorded photographic film are shown- In. Fig. 7, the reference character 33 represents the differentially disposed perforations on the record card 32,

I whereas in Fig. 8, the reference character "I represents the differentially disposed control spots, or light modifying areas, on'the control film record I30.

2 Record card feeding means Referring now to Figs. 1 to 4, it will be shown, how the card feed magnets 20 control the operation of the record card feeding means. A motor 2I (Fig. 11a) suitably mounted in the machine, is eflective to rotate the shaft 24, by means oi the interconnecting belt 22,'pulley 23, pawl 25 secured to said pulley, and ratchet 26 which is secured to shaft 24, and engaged by the pawl 23. In this manner, the shaft 24 is rotated continuously as long as the motor is operated. Gear 21, attached to the shaft 24, is efle'ctive to drive gears 23 and, 23 by means of the interconnecting gears "and II, both of which are affixed securely to shaft 32. -Gear 23 1s secured to shaft 33, thus it is seen, that shafts 32 and "33 are arranged to be rotated continuously, similarly as shaft 24, as long as the motor is operated." A

single tooth ratchet 33 is secured togear 28, both gear andratchet being rotatably mounted on the supporting shaft 34, and to which shaft an arm 33 is attached. A spring actuated dog 31 is pivotally mounted onthe arm 36,'and arranged-to be held 'outof engagement with the ratchet 35 (by the armature 33, which armature is associated with, and controlled by, the magnets 23. understood, that upon energization of themagnet 20, the associated armature 33 is displaced suiiiciently out of the path of dog 31 and arm 38, to release these elements, and permit the dog 31 to engage the single tooth of ratchet 35, thus effecting rotation of the shaft 34, by-means of the ratchet and associated gearing. Shaft 34 is rotated, as long as the magnet '20 remains energized, and in turn, effects rotation of gear 33 attached thereto, gear 43 and shaft 4| to which the last mentioned gear is secured. I

Complementary cams 42 and 43 (see Fig; 5) are mounted on shaft 34, and are arranged to displace the two armed lever 44 on shaft 45 thereby rocking shaft fl andthe sector arms 43 (Fig. 1) attached thereto. The said'sector arms are provided with gear teeth which mesh with racks on the card picker slides 41. 'A knife edge 43, attached to the slides, is adapted to engage the bottom card in the supply magas zine, or hopper. M, and displace the card to the right (Fig. 1), when the piclner slide is reciprocated by the cams 42 and 43 on shaft. The ratio of the described gearing is suchthat gear 23 rotates onerevolution for each card cycle. Associated with the card hopper M are the contacts 54 (Fig. 1a) controlled by the lever 55, which contacts are adapted to remain closed,

as long as cards are provided in the supply hopper, and upon exhaustion thereof, the said lever is permitted to swing in a clockwise direction to open the said contacts. r a

Upon deenergization of the magnet", the spring-urged armature 33 is positioned in the path of dog 31 and arm 36, so that disengage- From the description thus far, it is' ment of dog 81 and ratchet 88 is effected. A

locking lever 48 is provided to maintain arm 38 in a predetermined position, thus locking the shafts 84 and 4| in the normal D" or home pc- 5 sition (seeFig.l).

It should be mentioned that cam elements 80 are provided on the shaft 4| (Figs. 2, 2a, and 4) to control the associated cam controlled contacts P| to P--8; and, that shaft 83 carries cam elements 8| to control the associated cam controlled contacts C-l to 0-. Upon shaft 38 (see Fig. 4) a suitable cam 88 (see Fig. 11b) is mounted, which cam is adapted to operate the associated contacts 51, at different times, during the machine cycle (see Fig. 10), and in addition thereto, the brush 88 of a well-known type of impulse emitter 88 (see Fig. 11b) is secured to the said shaft, so that the individual conducting segments 60 are connected to the common conductor 8|, at different times, during the machine cycle, by means of the rotated brush, the purpose of which will be described later.

It has now been shown, how the record cards 82 are fed singly from the supply hopper M, by means of the card picker mechanism, whenever the control magnet 28 is energized. For further detailed description of the card feeding mechanism reference may be made to U. S. Reissue Patent #21,133 dated June 2'7, 1939, wherein elements similar to those just described are shown in detail. The individual record cards are now displaced and fed to the first set of feed rolls 88 and 8|, which in turn, feed the cards past the card recording or perforating station. It will be shown, that the individual cards are positioned intermittently, by the feed rollers, not

ly past the card recording station, but also PL. the card sensing station. This mechanism will ow be described in conjunction with the 40 card i rcording or perforating means.

Record card recording means Referring now to Fig. l, the card recording station is shown to comprise recording means, 45 illustrated in the form of record card perforating plungers 85, the operation of which are selectively controlled by the magnets 88. The said magnets, upon energization, select the associated plungers so that, during the operation of the op- 50 erating bar 61, the bar depresses or operates all the selected plungers, and thereby effects perforation of the record card. This opeation is explained in detail, in the patent referred to hereinabove, and therefore the following brief de- 55 script-ion thereof is deemed sufficient. It is well known, that an individual plunger 65 and controlling magnet 86 are provided for each columnar area of the card, and that all the selected plungers are operated or'depressed for all go columnar areas simultaneously. It will be explained shortly, how the'diiferent index point positions of the cards are fed, intermittently, to the punching station, and that the perforating thereof is effected while the cards are stationary 65 thereat.

The said plungers are shown provided with in- 'dividual spring-urged pivoted interposer pawls 88, which are connected to the armatures 89 of the magnets, by call wires 18, so that, upon ener- 70 gization of a magnet, the connecting call wire is effective to swing the pawl 68 to the right, as viewed inFig. 1, positioning the said pawl in the path of the operating bar 61. Upon depression of the said bar, which is adapted to co- 75 operate with the notch 88a in the pawl, the related pawl is caused to be depressed to perforate the record card accordingly, and is then quickly withdrawn therefrom to permit feeding of the card to the next index point position.

The operating bar 81 is supported by a control bail 1| which is suitably pivoted on studs 12. The control bail is attached to arm 13, by means of an adjustable turnbuckle connection 14, said arm 13 being secured to shaft 15 which is also provided with an arm 16. An eccentric 11 'is suitably disposed and formed on the shaft 24, which eccentric is encircled by an arm 18, the upper end of which is pivotally connected to the said arm 16.

It is now seen that, since the eccentric 11 is positioned on the constantly rotating shaft 2|, shaft 15 and arm 13 are rocked to depress, at periodic intervals, the bail 1| and bar 81. As the said bail and bar are reciprocated, any of the pawls may be positioned by the call wires so as to effect engagement of the pawls and bar. Then, the connected pawls and plungers are depressed to perforate the card, and thereafter withdrawn immediately therefrom to permit the feedng of the card. Referring to Fig. '1, a facsimile of a portion of a perforated record card 52 is shown, the index point positions for several columnar areas are shown to be provided with perforations 53, at different positions in the columnar areas, to represent different data representations.

The feeding of the cards to, and from, the punching station is effected by the feed rollers 88', 8|, 82 and 88. The cards are fed, intermittently, by rollers 80 and 8|, between a stipper plate 84 and die plate 85, through which plates the plungers are adapted to be positioned.

The mechanism for operating the said feed rollers is as follows-referring now to Figs. and 6, it is seen, that the continuously rotated gear 21 (also see Fig. 2) is provided with a Geneva roller 86 and segment 81, which cooperate with a Geneva disc 88 fixed on shaft 89. The Geneva disc is provided with seven radial slots, so that one revolution of gear 21 will rotate the shaft 88 one-seventh of a revolution, which partial revolution corresponds to a movement of one cycle point of the record card. Shaft 89 rotates continuously, with an intermittent motion, as long as the motor 2| is operated. Rotatably mounted on the shaft 89 is a gear 90, which has affixed thereto a single tooth ratchet 9|, and secured to the shaft 88 is an arm 92, upon which a spring-urged dog 93 is pivoted. The spring-urged'dog normally tends to engage the ratchet 9|, however, disengagement of the dog and ratchet is effected by the lever 94 and attached roller 85, which roller as shown in Fig. 5, engages the tail of the dog to position it, so as to prevent engagement thereof with the ratchet. When the said lever and roller are positioned to the right, as viewed in Fig. 5, and out of the path of the dog, the dog and ratchet are permitted to be engaged, thereby effecting rotation of gear 90 which is arranged to drive gears 96 and 91, which gears are fixed to shafts 98 and 98, respectively. Suitably disposed on shafts 98 and 89 (see Figs. 1 and 2) are gears I00 and II, arranged to engage gears I02 and I03, which are pinned to shafts IM and I05, respectively. Shafts 88 and HM carry the first pair of feed rollers 80 and 8|, respectively, whereas, the second pair of rollers 82 and 83 are carried by shafts 89 and "I8, respectively. I

It is evident now, that whenever the lever 94 ing the driving ratchet ll. 25 said magnet be energised, cams I and III are as it, lb, and 11a) isdisplacedoutofthepathofdogll. engage- -ment of the dog and ratchet If is eifectedto drive the feed rollers II to Cl. intermittently, .by means of the described gearing. As mentioned 5 herelnabove, the gear ratio is such. that for each movement of shaft ",the feed rollers are rotated to an extent suiilcient to displace the card life cycle point which displacement is equivalent to the distance. between index point positions on the record card. The lever I4 is displaced,

so asto release the dog It, by the complementary cams Ill and Ill positioned on shaft It, which cams are engaged by the rollers Ill and ill carried-by the horizontal portion oflever II. It is remembered. that the rotation of shaft as is controlled by the magnet 20, and that, whenever this, magnet is energised. shaft u is rotated continuously by the shaft 24 and associated gearing, described hereinabove. The cams its and II] are designed. so that, if the magnet fl is not energized and the shaft It is not rotated, lever 04 is positioned in the path of the dog It, thereby preventing the dog from engag- However, should the turned, lever 04 displaced, permitting engagement of the said dog" and ratchet, and'establishing a driving connection between the interm'ttently driven shaft II and gear II for effecting to intermittent movement of the card feed rollers Recordcardseminomeons Referring nowto Fig. l. the record cards are fed from the recording station to the sensing station, by the rollers If and 88, through the guide plates Ill, and past the suitably mounted sensing brushes III (also see Fig. llb) cooperating with the conducting roller Ill. It is understood that the index point positions of the intermittently fed cards are positioned'properly at the sensing station, so that, whenever perforations so are present in the cards at particular index point positions, the corresponding sensing brushes are adapted to extend therethrough and engage the conducting roller, thereby completing the'circuits associated with said brushes and roller. The

so controlling circuits thus established will be described later herein. A i'acsimfle of a portion of a suitable perforated record card I! is shown in Fig. 7 provided with the differentially positioned perforations II.

00' It should be mentioned, that at the sensing station a suitable and well known type of lever H. (see Fig. 11:) is provided (01 controlling the associated card lever contacts I". Whenever a card is fed to, and present at. the sensing station, the said card lever is operated, by the cards,

to close the card lever contacts. and whenever no cards are present to engage the card lever, the card lever contacts are opened.

Record cord stacking means From the sensing station, the cards are fed to a hopper N (Fig.1). by means of the card stacker drum ill, and associated feed roller lll,and feed rollers I21 and I28. The said drum 'andfeed 18 rollers are operated'continuously, with an intermittent motion, and in a synchronous relationshipwiththefeedrollerssltoll.

Referringnow to Figs. 2, 5 and 6, it is remembered, that shaft II is rotated continuously with an intermittent motion. This shaft has secured theretogear it, which drives gears Ill and III both of which gears are mounted on a commonhub III, which is rotatably supported by shaft as. By means of the gearing. comprising the gear III pinned to idler shaft Ill, gears Ill and Ill pinned to shaft III, the gearlllis elective to rotate the gear ill and shaft I upon which is mounted the stacker drum ill (see Fig. l).

Pinned to the opposite end of shaft Ill is a gear. not shown, but similar in size to gear I".

and which is arranged to drive gear in and its related shaft I", upon which the feed roller Ill (Fig. 1) is mounted; thus, itis seen, that the stacker drum and associated feed roller are rotated continuously, with an intermittent motion, as long as the 'motor is energized, andin synchronism with the operation of the feed rollers It to It, since thecontrolling drive shaft II is the common drive for both the controlling gearings. The gear ratios between gears I24 and III are such that one-seventh of a revolution of gear as will displace the upon which the cards are held, one cycle point.

Gear I also drives gear .li'l and related shaft m, upon which shaft is mounted gear m which drives the gearing, comprising gears m and ill pinned toshaft I42, gears ill and l, the latter gear being pinned to shaft Ill, Upon the sh'aft I42, a feed roller l2}, (li'lg'. l) is mounted, and by means of a gear similar to gear ill, mounted on the shaft I", the gear I andrelated shaft in are driven; feed roller III is mounted on shaft I" and rotated thereby.

From the feed rollers If! and If! (Fig. 1) the cards are stacked in the hopper N, whereat provision is made to insure proper insertion of the cards in the stack, by providing a rubber stacker roll I mounted on shaft lll which when rotated, by means of the said shaft, -1rges the cards tothe rightasviewedinl 'lg. 1.

. Referring now to Fig. 9, the stacker drum III, mounted on and rotated by shaft Ill, is shown to be provided with a plurality of pivoted gripping fingers us. These fingers are urged into card gripping position by the spring pressed plungers ill. Fixed face cams lllare provided, to be suitably disposed so as to cooperate with the associated fingers, to effect their opening and closing at the proper time. The timing of the fingers is such that the record card is gripped, after it passes the feed roller ill, and held securely to the drum as it rotates to further advance the card, and finally releasing and discharging it to the feed rollers if! and I 3.

Film sensing and recording means With reference now to Fig. 1, the film sensing means is shown to comprise generally, a light source comprising the individual lamps Ill supported in suitable enclosures, generally indicated I", from one side of which, individual light conducting quarts rods ll'l are provided, and which are supported by the frame member Ill. Mount ed in the same plane as member I is another frame member I'll for'supporting the quartz rods ll! extending to individual .light responsive means I", such as photo-cells. The said memberg Ill and I are provided with a small gap between them through which the photographic film I" is fed. In the instant application, the film is fed intermittently to, and from, the sensing station, by means to be described later herein, so that the index point positions of the film are presented successively thereto. Referring to Fig. 8, a facsimile of a portion of the film record it. is shown, wherein the index points l8| are shown differentially disposed in various index point positions in the columnar areas. The quartarods I11 and I82 are spaced in therespective members I84 and I'll so that they correspond to the individual columnar areas in position.

The method of sensing the data representations on the photographic film record will now be understood, assuming that the index points, representing the data representations, in the form of control spots are presented, intermittently and successively, to the sensing position or station, and that the individual light sources I15 are continuously energized, it is seen that, when no control spots appear at the particular index point positions analyzed, the light conducted from the light source to the film record by the one group of quartz rods is permitted to permeate the film, and be conducted by the other group of quartz rods to the related photo-cells thereby conditioning the photo-cells, in a predetermined manner. However, whenever control spots appear at the sensing position, the corresponding beams of light conducted thereto are modified or blocked off, so that the light no longer is conducted to, and impinged upon, the related photo-cells, thereby controlling the action or operation of the photocells. It is obvious, since the said control spots disposed on the film record in different index point positions. and since the index point positions are analyzed successively, that the different beams of light are modified, at differential times, for controlling the operation of the related light responsive means.

The method of recording the data representation in the form of difierentially positioned control spots is now evident, since the only requirement necessary for this operation is forthe light sources to be normally deenergised. Now, as the film record is fed to the sensing station intermittently, the individual light sources are controlled, so as to be energised at different times, thus permitting the beams of light to be conducted and directed. by the quartz rods I'ILto the corresponding columnar areas, thereby effecting recording upon the light sensitive photographic film, at diflerent positions, in the said columnar areas corresponding to the timed intervals at which the related light sources are energised.

' Film leading means Referring now to Figs. 1 2 and 4. the means for feeding the photographic film supply reel 2|. intermittently to, and from the sensing or recording station. and to the take-up reel 2" comprise the following gearing, which gearing is controlled by the shaft I42, which as,

, normally, when the magnet is deenergized, is

adapted to be positioned in the path of the said arm and dog, thereby preventing engagement of the dog 2" and ratchet 2". However, upon energization of the said magnet, the armature is displaced sufilciently to release the dog, thereby permitting engagement of the said dog and ratchet, thus effecting rotation of shaft 204 by means of gears 202 and 203.

Secured to shaft 204 is the gear 2I0 engaging gear 2, which is fastened to shaft 2i2, upon which shaft 2 i2 is mounted the film drive sprocket 2I3. Also secured to shaft 2l2 is a pulley 2 which, by the connecting belt 2l5, is adapted to rotate the shaft 2l6, upon which the take-up reel 20 is mounted. Thus, it is seen, that the film I is fed to, and from, the sensing and recording station intermittently, by means of the driving sprocket 2 l3 and the described gearing. It should be mentioned, that contacts 2I8 are provided, and adapted to be closed by the lever 2|9, whenever the film record I80 is present in the sensing unit, and are arranged to be opened whenever the film record supply is exhausted.

Certain circuit controlling elements are provided, which will now be described, and which must be operated in synchronism with the feeding of the film, but are shown operated with a uniform motion instead of an intermittent motion, therefore, the following controlling and gearing means is provided. Referring particularly to Fig. 4, it is seen, that the continuously rotated gear 28 has secured thereto an additional single tooth ratchet 220, which is arranged to cooperate with a dog 22l, pivotally mounted on the arm 222, which arm is secured to a gear 222 rotatably mounted on shaft ll. Normally, the dog and ratchet are maintained disengaged, by means of the armature 224 of magnet 22!, in a manner similarly as described hereinabove with reference to thesame type of clutch. Upon energization 0f the magnet, the armature 224 releases the dog 22! to engage the ratchet 222, thus efiecting rotation of gear 222 and the gear 22 engaged thereby (Fig. 2). Gear 228 is secured to shaft 221, which carries the cams 222 for controlling the associated contacts F, the p p se of which will be understood as the description Operation of machine Referring now to the circuit diagrams. particularly Figs. lia and lib, the operation of the data reproducing machine will be'described. The descrlption to be given first will relate to sensing the perforated cards, and reproducing the data representations sensed upon an unrecorded pho-- tographic film record, in the form of differentially positioned control spots. To effect this type of data reproduction, the machine must be conditioned accordingly, therefore, let it be assumed that the main switch MS is closed, that the control switches S-l to S-lll are positioned in the 01'" positions as shown, that perforated record cards are provided in the supply hopper M, that the unrecorded photographic film II! is properly inserted in the machine, and that the start key is depressed to close the associated contacts SK-l.

A circuit is then completed from conductor 2", to coils of relays R-l, R-2, contacts SK-l, and contacts SK-2 of the stop key to the con ductor 25!, causing the said relays to be energized. Upon energization of relay Rr-l the con tacts Br-lfl are closed to complete a circuit from. the power supply source to the drive motor 2|, thereby eflecting operation thereof, to drive the associated gearing described hereinabove. Upon energization of relay 3-2, a holding circuit tacts R-lanow closed, through the normally closed cam operated cuntactsG-I. The contacts R-Ib are also closed, upon energization of relay 3-2, to eflect energization of card feed control magnet 20-, by the circuit completed by the said contacts, which is as follows: conductor 250, coils of magnet 20, switch Si, contacts R-Ib, and the normally closed cam operated contacts C-l to conductor 25L Upon energization of magnet 20, the shaft N is rotated to operate the card picker mechanism, thereby effecting the feeding of a card to the feed rollers 80 and 8i. The gearing driving the feed rollers is also operated, when magnet II is energized and shaftv 34 is operated. Thus, the record card is fed, intermittently, up to the card perforating statin,'and thereby causes the contacts O to be closed. A circuit is then com- Pleted, during this machine cycle, from the power V supply conductors 250 and 2H to the coil of relay R-Q, energizing said relay, and causing the contacts R-Sa, R-Ib, and R.3c to'be closed. The P--2 cam contacts areclosed at the time the wntacts III! are operated, thus a circuit-is es-' tablished from conductor 250 to the coil of relay R-l, contacts l-t-Jc, switch 8-4, and contacts P-l to conductor I, energizing the said relay. A holding circuit for this relay is completed, upon closure of the associated contacts R-9a, through the switch 8-5, and cam contacts P-4 which are closed at the time contacts H0 are closed, and are maintained in this condition theremaining part of the machine cycle, (see timing chart, Fig. 10). This condition occurs near the end of each machine cycle, so it is understood, that relay 3-! is energized, near the end of each machine cycle, and maintained so until after the beginning of the following machine cycle.

The purpose of the circuit arrangement (shown in Fig. 11a) is to cause operation of the relays R' -3, R-l, lip-I, R-8, and R-Q so that the contacts R-Ia, R-la, R-Ia, 3-, and R-Ob, which are connected in series with the contacts -near the end of each machine cycle) so that relays 3-! and R-I are maintained energized, thus providing continuous operation of the machine.

However, when first starting the machine, it will be necessary to hold the starting key depressed, for several machine cycles until all the control circuits are properly conditioned for continuous operation. This is obvious, since at the end of the first machine cycle, the first card is Just approaching the card perforating station. This being the case, it is seen, that contacts Ill at the card sensing station are still open, thus preventing operationv of relay 3-4, and thus preventing continuous operation of the machine at this point.

Assume that the start key is kept depressed, so that another machine cycle is completed, the feed rollers 82 and II are then effective to feed the first cardup to the sensing station, past the card lever H8 sufllciently-to close the contacts Ill, but not under the sensing brushes as yet. The sensing operation of the first card occurs I during the third machine cycle. Now, at the 2,224,701 therefore is established by the associated conslnce contacts 54 and 2" respectively are closed, these contacts are controlled by the supply of cards in the hopper M, and the film record I" in the machine.

It is seen now, that at the time, in the second machine cycle, the cam contacts 0-2 are opened that cam contacts P4 are closed. It was mentioned hereinabove, that shortly before contacts P3 are closed, the cam contacts P-2 are operated to energize the relay R-l, thus closing the associated contacts R-Ba at this time in the cycle, so that a holding circuit therethrough is established for the said relay, by means of the operated contacts P3; and as mentioned before, this holding circuit is maintained for the remaining part of the said cycle, and during the beginning of, the following machine cycle. Thus it is seen, that from now on, during each machine cycle, a circuit is completed from conductor I" to coil of relays R! and R-2, contacts R-Ia, lit-4a, Rr-JG, R-la, RF-Ja, R-Ob, switch 8-4, and normally closed contacts SK-I of the stop key, to conductor III. This circuit is completed at a time in the cycle when cam contacts 'C-2 are opened, thus, the relays R-l and 3-2 are maintained energized for the beginning of each following machine cycle. Also, near the end of each machine cycle, the cam contacts C-l are closed, and maintained so, until afterthe beginning of the following cycle, so that the magnet 20 is energized at the end ofeach cycle, thus eilecting a card feeding operation for each machine cycle. The machine is now conditioned for continuous operation, and at the beginning of the third cycle the card sensing operations are effected. Therefore, it is evident at this time, that it will be necessary to render the film feeding mechanism operative, so that the film is positioned, intermittently, in synchronism vwith the progression of the record card. This is effected as follows:

Near the end of each machine cycle, the cam contacts 0-3 are closed, therefore, a circuit is completed from conductor 25. to the coil of relay R--I, to contacts R-lb, and cam contacts 0-4 to conductor III, energizing said relay; at l ductor ill, energizing this relay." These circuits. are maintained for the remaining'part of the said cycle, and during the beginning of the following cycle, by means of cam contacts 0-4. Beforethese said cam contacts are opened, during the said following cycle, contacts P-l are closed to maintain the relays R-5 and R-l energired, through the associated contacts R-la and Rw-b respectively, all during the sensing and recording portions of each cycle. Contacts 11,-, Me, RP-sa and 11-04, a lc, R-ld to 3-". associated with said relays, are therefore operated, at all times, during the sensing and recording portions of the machine cycles.

'Closure of contacts R-la completes a circuit as follows, near the end of each cycle, from conductor I" to coils of magnets "I and "I, contacts R-Oa, switch 8-2, contacts 3-217, and

cam contacts 0-! to conductor flh'energizing said magnets. Energization of magnet 20. per-- mits the film feeding mechanism, described hereinabove, to become effective to feed the film record I, intermittently, to its sensing and recording station, in timed relationship, with the feeding of the record cards I! pastv the sensing station therefor. Energization of magnet 22' is effective to render the control shaft 221 operative, to control the timing of the F cam contacts, which are controlled by cams 22! mounted thereon, the purpose of which will be described later.

The machine is now conditioned to sense the first card, and all cards following thereafter, successively, for controlling the film recording mechanism. It is now seen, as the individual record cards are fed past the record sensing station, the data representations represented by the differentially positioned perforations thereon are sensed, by means of the sensing brushes H6 cooperating with the common conducting roller ill, to colnpletq the following circuits, at different times, depending upon whether or not perforations in the various columnar areas are presented thereto: from conductor 250 to switch S--'I, conductor 262, individual light sources i'li, conductors 253, sensing brushes Iii, conducting roller Ill, conductor 254, cam contacts P-! which are closed during the sensing portion of the machine cycle, contacts R-ic now closed, contacts 51, which are closed during each card index point position (see Fig. 10) to conductor 25!, energizing the said individual light sources in accordance with the perforations sensed on the record cards. Obviously, as many columnar positions can be sensed, on the record cards, as desired for controlling corresponding individual light sources for reproducing all the sensed data representations on the photographic film record.

It was mentioned hereinabove. that upon energization of the film feed control magnets 208, the photographic film record I80 is fed, intermittently, to the recording station, in synchronism with, the intermittent feeding of the record card to the card sensing station, so that, for example, when the 9" index point positions on the card are presented for sensing thereof, the film record is fed to its recording station, so that the 9 index point position thereof of the individual frame, or portion of the film record, is presented at the film recording station. Therefore, at the particular timed intervals the light sources are energized, by means of the card sensing circuits, the light sensitive record is exposed to the light rays, at such intervals, to effect recording thereon in the form of control spots, as indicated in Fig. 8, at difierential positions in accordance with the data sensed. Further explanation of this form of sensing the record cards, and recording the data, in the form of control spots on the film record, is deemed unnecessary in order -to comprehend fully the scope of the instant invention, with this exception, that provision is also made, whereby additional data, in addition to the sensed data, may be recorded in various columnar areas on the film record as desired, by means of manually controlled data storing devices. These devices are represented generally by the reference character 2, in Fig. 11b, and each comprise a common conducting ring 2", and individual conducting segments 2" which are connected as desired by means of the cooperating brushes 258. The brushes are positioned manually to represent any desired data, and are effective. by means of the common emitter I, to initiate control impulses at a diflerential times to correspond to the stored data for controlling, in this illustration, the individual light sources I15. Assume now, that certain orders of the said storing devices are positioned as desired, representing predetermined data to be recorded on'the film record, at the same time, and in addition to the data sensed on the record cards. It is seen, that circuits are completed from conductors 250 and 252 to the individual lights ill, conductors 259, contacts R-Bd and R'8f (which are closed during the sensing portion of the cycle), data storing devices 255, emitter 59, switch SF-iil, contacts F S (closed during the sensing cycle), contacts 51 and conductor 25L energizing the said light sources, whenever the rotating brush 58 engages conducting segments 60 which are connected to the conducting segments 2", which segments in turn are connected to the associated common conductor Si by the positioned brush II. The brush 58 of the emitter is rotated, in synchronism, with the card sensing operations, by means of the shaft 33, so that during the intervals the "9" index point positions are sensed, the emitter is effective to read out the "9 position of the data storing devices, thus being effective to establish circuits for controlling the energization of the light sources for recording the stored date, upon the film record, in the form of differentially positioned control spots;

In view of the detailed description just set forth, and since the driving mechanism, feeding mechanisms, and control circuits are operated and conditioned, in the same manner, for reproducing the data sensed upon recorded film records on the blank record cards, in the form of perforations, the following brief description 15 believed to be sumcient. Assume now, that all the control switches S-i to S-iil are positioned in the FC position, and that the start key is depressed to close the contacts SK- I, long enough to condition the machine for automatic operation. l br this description, reference should be made to the circuit diagrams shown in Figs. 11a and 110. operation, whereby the recorded film record is sensed and the sensed data is reproduced or perforated on the blank record cards accordingly, that, upon feeding the film record, the record cards must be presented at that time at the punching station. As it will be seen from the description to follow, the film record must be properly positioned in the machine, and two blank frames thereof are fed to the film sensing station upon starting the machine in operation; of course, it will be evident too that in the event this is not done, no harmful results are effected with respect to the instant invention. the sug-* Rl and R.-2 are energized, causing operation of the driving motor 2i, and associated searing, by means of operated contacts R-ia and Lin ergization of the control magnets 20!; and 225, causing operation of the film feeding mechanism, and the F cam shaft, as described hereinubovc. At this time, cam contacts C-| are closed to energize relay R-l i, and to establish a holding circuit therefor, through the closed contacts 32-- i la and cam contacts F-5. Thus, it is seen that, upon depression of the start key, the card feed magnet 20 is energized by the following circuit: from conductor 250 to coils of magnet 20, contacts Rp-lib, normally closed contacts R- 3d. switch S2, contacts R2b, and contacts C-i to conductor 25!, thereby effecting a card feeding operation. Near the end of the first machine cycle. the contacts I ID are operated by the card fed there past to energize relay R-3, and cause the contacts R-Je to be closed, thus opening the circuit to the feed control magnet 20 for the following machine cycle. This is effected, since It will be understood, for this type of contacts R-lllb are not closed until near the end of the said following cycle, when cam contacts F-l are closed to establish a circuit from conductor 250 to coil of relay R-IO, contacts R-l lo and R3j and contacts F-3 to, c nductor 2H, energizing said relay, and establishing a holding circuit therefor through contacts R-Hla and cam contacts F-4. Therefore, at the beginning of the third machine cycle, the magnet is again energized through a circuit from conductor 250 to coil of magnet 20, contacts R-Jflb, contacts R3e, switch 8-2, contacts R--2b, and cam contacts C--I to conductor whereby card feeding operations are eifected, and by 15 means of the feed rollers 80 and 8|, the first card is now fed, intermittently past the perforating station.

Upon properly conditioning the machine with record cards, and a control film record, the con- 0 tacts II and 8, respectively, are operated to energize relays R1 and R8, respectively. Thus,

it is seen that a holding circuit, bridging the holding circuit including contacts (r-2, is established for relays R i and R.2, by the series circuit 2 arrangement of contacts R-2a., R-lb, R-Ib.

and R-|0c, thus establishing continuous operation of the machine. It should also be mentioned, that relay 3-! is energized at the beginning of each cycle, by means of the cam contacts 0-3, through the contacts R-4b to establish a holding circuit through the contacts R-Sa, and cam contacts P-l, which holding circuit is maintained throughout the entire sensing portion of the cycle, thus maintaining contacts Mb to R-Ud closed 85 during the said sensing cycle.

It should be understood now, that as the different index point positions are advanced to the punching station, the corresponding index point positions on the film record are sensed, for exdoample, as the 9" index point position on the film record is sensed, the 9" index point positions of the record cards are at the punching station under the perforating plungers. As the differentially positioned control spots on the film record are introduced at the sensing position, the presence of the control spots is effective to modulate or interrupt the impingement of the light rays from the light sources upon the related photocells. It is seen that, by means of switches 3-4 and 8-9, all the individual light sources are energized continuously. Whenever no control spots are present at the sensing station, the light rays are conducted by the quartz rods "1 and I82 therefrom through the transparency of the film I record to the related photo-cells, thus conditioning the said cells. These light responsive means I03 are connected to any well known type of amplifiers, generally indicated at 28!, which in turn are connected to control relays 2. The

amplifiers are adjusted so that, when light impinges upon the light responsive means, no current flows in the output circuit thereof, however, when the light rays are interrupted, by the presence of control spots on the film record, the

85 light responsive means and amplifier are conditioned so as to permit current to fiow in the output circuit of the amplifier units, this is a well known expedient in the art and needs no fur ther explanation.

It is understood now, that upon the presence of a control spot at the film sensing station, the corresponding light responsive means and amplifying means are conditioned so as to effect energization of the related relays "I when they, by

15 means of the associated contacts 262, complete circuits through the punch control magnets 66 as follows: from conductor 2" to switch S-I, punch magnets 66, contacts 262, common conductor 2, contacts 51 to conductor 25!, energizing the corresponding punch magnets 66. Energization of ii the said magnets operate the related punch plungers, to effect perforation of the record card, at the particular columnar index point positions corresponding to the index point positions in which the sensed control spots appeared on the film record. Further detailed description is believed unnecessary, possibly with the exception, that the manually set devices 255 may be used to effect perforating of additional data on the record card'to the data sensed on the film record. The 15 desired data stored in the devices is read out, at differential times, by the emitter 59 to complete additional circuits to the punch magnets as follows, from conductor 250 to switch S1, selected punch magnets 66, conductor 284, contacts Rf-5b 2 to R-Bd (closed during the sensing cycle), hand set devices 255, emitter I9, switch 8-), cam contacts P-4, and contacts 51 to conductor Iii, thus energizing the selected punch magnets, at differential times, corresponding to the data stored in 25 the hand set devices, thus effecting perforation of the recordcard in accordance with this data,

in addition to the sensed data disposed on the film record.

Summary It has now been shown and described, how the same data reproducing machine may be conditioned, whereby it is effective to sense data designations from one type of record medium and control the recording of corresponding data designations upon another type of record medium, or vice versa.

When conditioned for one particular type of operation, in accordance with the instant illus- 40 tion of the invention, it has been seen, that individual record cards bearing perforations at difierential columnar positions on the cards, when fed to the card sensing station, are sensed at differential times, thereby initiating electrical impulses ,45 at such times for controlling the photographic film record recording means. The electrical energy comprising the said impulses are then converted into light energy by energizing, at diiferential times, the individual light sources. The 50 light rays are then effective for controlling the photographic recording of the control spots upon the light sensitive web, or film, which isfed in synchronism with the feeding of the record cards,

so that the corresponding data, sensed on the 55 cards, are reproduced on the film in the form diflerentially positioned control spots.

It has also been seen, that upon proper conditioning of the machine, a photographic film control record having differentially positioned 50 data designations thereon, in the form of control spots or light modifying areas, which are positioned longitudinally of the film so as to represent by their relative positions the values of the designations, is fed to a sensing station, comprisinga light source and light responsive means, which are influenced by the data designations on the film record at such times, whenever the control spots are fed into the path of the light source 70 and efiect modification of the lightrays. light responsive means are eflective, whenever such data designations are sensed, to initiate electrical impulses. which in turn are effective to, control therecord card perforating means so as to" perforate the blank record cards fed thereto, in synehronism with the feeding of the film record, and thus reproduce the data, sensed on the film, upon the record cards in the form of differentially positioned perforations in various columnar areas.

It has also been seen, that manually settable devices are provided, which have elements which are positionable so as to represent any desired data, and are effective to control the record medium recording means for the several types of reproducing described, so as to effect recording of the data, upon the selected record medium. corresponding to that set up in the manually settable devices, in addition to the recording of the data corresponding to the data sensed on the related record medium.

while there has been shown and described and pointed out the fundamental novel features of the invention as applied to a single modification it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention.
